The invention discloses a DNA (deoxyribonucleic acid) combined bar code for identifying nine types of dalbergia wood. The DNA combined bar code is formed by more than two of bar code sequences trnL, trnH-psbA, trnV-trnM or ITS2. The invention also discloses a method for identifying the nine types of dalbergia wood. According to the DNA combined bar code and the identification method of the DNA combined bar code provided by the invention, accurate identification on the nine dalbergia woods can be realized, and the problem that a species level of the dalbergia wood cannot be identified by adopting a conventional wood identification method is solved, so that a high-efficient and reliable identification method is provided for wood trade law-enforcing departments such as customs and quality inspection and quarantine and wood management trading persons, and a technical support is provided for execution of Convention on the International Trade in Endangered Species (CITES); therefore, the DNA combined bar code has a higher application value.
